ea23ec82c2 Remove GUC USERLIMIT variable category, making the affected variables
plain SUSET instead.  Also delay processing of options received in
client connection request until after we know if the user is a superuser,
so that SUSET values can be set that way by legitimate superusers.
Per recent discussion.

98e8b48053 Create 'default_tablespace' GUC variable that supplies a TABLESPACE
clause implicitly whenever one is not given explicitly.  Remove concept
of a schema having an associated tablespace, and simplify the rules for
selecting a default tablespace for a table or index.  It's now just
(a) explicit TABLESPACE clause; (b) default_tablespace if that's not an
empty string; (c) database's default.  This will allow pg_dump to use
SET commands instead of tablespace clauses to determine object locations
(but I didn't actually make it do so).  All per recent discussions.

80559fa9e9 I found a corner case in which it is possible for RI_FKey_check's call
of HeapTupleSatisfiesItself() to trigger a hint-bit update on the tuple:
if the row was updated or deleted by a subtransaction of my own transaction
that was later rolled back.  This cannot occur in pre-8.0 of course, so
the hint-bit patch applied a couple weeks ago is OK for existing releases.
But for 8.0 it seems we had better fix things so that RI_FKey_check can
pass the correct buffer number to HeapTupleSatisfiesItself.  Accordingly,
add fields to the TriggerData struct to carry the buffer ID(s) for the
old and new tuple(s).  There are other possible solutions but this one
seems cleanest; it will allow other AFTER-trigger functions to safely
do tqual.c calls if they want to.  Put new fields at end of struct so
that there is no API breakage.

12a47c6aca Disallow referential integrity actions from being deferred; only the
NO ACTION check is deferrable.  This seems to be a closer approximation
to what the SQL spec says than what we were doing before, and it prevents
some anomalous behaviors that are possible now that triggers can fire
during the execution of PL functions.

f9259bd563 Update wording:
* Allow a database in tablespace t1 with tables created in tablespace t2
  to be used as a template for a new database created with default
  tablespace t2

  All objects in the default database tablespace must have default tablespace
  specifications.  This is because new databases are created by copying
  directories.  If you mix default tablespace tables and tablespace-specified
  tables in the same directory, creating a new database from such a mixed
  directory would create a new database with tables that had incorrect
  explicit tablespaces.  To fix this would require modifying pg_class in the
  newly copied database, which we don't currently do.

4347cc2392 Allow background writing to be shut down by setting limit values to zero.
This does not disable the bgwriter process: it still has to wake up often
enough to collect fsync requests from backends in a timely fashion.  But
it responds to the recent gripe about not being able to prevent the disk
from being spun up constantly.
